The world is experiencing the expansive spread of severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) in a global pandemic that is placing strain on health care, economic, and social systems. Commitment to implementing proven public health strategies will require bold public health leadership and courageous acts by politicians. Developing new innovative communication, mitigation, and health care approaches, particularly in the era of social media, is also clearly warranted. We believe that the best public health evidence must inform activities in three priority areas to stop this pandemic (1) coordinated and consistent stay-at-home orders across multiple jurisdictions, including potential nationwide mandates; (2) rapid scale-up of SARS-CoV-2 testing; and (3) improved health care capacity to respond. This editorial outlines those areas, the rationale behind them, and the call for innovation and engagement of bold public health leadership to empower courageous political action to reduce the number of deaths during this pandemic. ©Jodie L Guest, Carlos del Rio, Travis Sanchez.

Interestingly, both of these compounds are also drugs of abuse. Intravenous ketamine, a dissociative anesthetic that induces complex downstream effects via NMDARs, rapidly reduces depressive and suicidal symptoms in treatment-resistant depression (TRD), as demonstrated by several trials. Recently, the United States Food and Drug Administration (FDA) approved an intranasal version of ketamine (esketamine) for TRD. The United States Drug Enforcement Agency (DEA) lists ketamine as a Class III scheduled drug (moderate-low potential for physical and psychological abuse). The FDA has established a Risk Evaluation and Management Strategy (REMS) program to ensure proper drug storage, handling, dispensing, and monitoring intranasal esketamine to minimize misuse/abuse opportunities. Nitrous Oxide is a colorless, odorless, gas that has been in medical use for over 150 years. The mechanisms of action of nitrous oxide are not fully understood; however, it is known to act as a non-competitive inhibitor of NMDA-type glutamate receptors. Currently, nitrous oxide is used for inhalational general anesthesia and analgesia for short procedures. Inhaled nitrous oxide is also used recreationally, primarily by teens and young adults, but is not believed to have strong addiction potential. In contrast to ketamine, nitrous oxide is not a controlled substance and can be legally purchased without a prescription. A recent double-blind, prospective, cross-over study demonstrated that nitrous oxide reduced depressive symptoms in a group of severely ill TRD patients. Though this is a promising initial study, further investigation is needed. BACKGROUND There is a lack of information on the natural history of asymptomatic carotid artery stenosis (AsymCS) associated with cardiovascular diseases that require surgery. The aim of this study was to investigate risk factors for postoperative ipsilateral ischemic stroke and all-cause mortality after cardiovascular surgery in patients with AsymCS. METHODS Among 2158 patients who underwent cardiovascular surgery, 150 patients with AsymCS who didn't undergo carotid revascularization were included. The relationships between preoperative factors, including carotid intraplaque hemorrhage (IPH), and postoperative ipsilateral ischemic stroke and all-cause mortality were analyzed retrospectively. RESULTS During the median follow-up of 1087 days of 150 patients with 19 IPH, 12 (8.0%) and 21 (14.0%) encountered ipsilateral infarction and all-cause mortality, respectively. Multivariable Cox regression analyses indicated that IPH was significantly predictive of both ipsilateral infarction (hazard ratio [HR] 21.31, 95% confidence interval [CI], 4.98-91.17; P ≤.001) and all-cause mortality (HR 4.64, 95% CI, 1.61-13.34; P = .004). CHIR-124 Another significant factor was peak systolic velocity for ipsilateral infarction with the cutoff velocity of 227 cm/s by the receiver-operating characteristic curve. CONCLUSIONS In this cohort of patients with AsymCS undergoing cardiovascular surgery, IPH had a close connection with a high risk of both postoperative ischemic stroke and mortality after cardiovascular surgery. V.Lysine acetylation is one of the most important post-translational modifications and is involved in multiple cellular processes in plants. There is evidence that acetylation may play an important role in light-induced de-etiolation, a key developmental switch from skotomorphogenesis to photomorphogenesis. During this transition, establishment of photosynthesis is of great significance. However, studies on acetylome dynamics during de-etiolation are limited. Here, we performed the first global lysine acetylome analysis for Zea mays seedlings undergoing de-etiolation, using nano liquid chromatography coupled to tandem mass spectrometry, and identified 814 lysine-acetylated sites on 462 proteins. Bioinformatics analysis of this acetylome showed that most of the lysine-acetylated proteins are predicted to be located in the cytoplasm, nucleus, chloroplast, and mitochondria. In addition, we detected ten lysine acetylation motifs and found that the accumulation of 482 lysine-acetylated peptides corresponding to 289 proteins changed significantly during de-etiolation. These proteins include transcription factors, histones, and proteins involved in chlorophyll synthesis, photosynthesis light reaction, carbon assimilation, glycolysis, the TCA cycle, amino acid metabolism, lipid metabolism, and nucleotide metabolism. Our study provides an in-depth dataset that extends our knowledge of in vivo acetylome dynamics during de-etiolation in monocots. This dataset promotes our understanding of the functional consequences of lysine acetylation in diverse cellular metabolic regulatory processes, and will be a useful toolkit for further investigations of the lysine acetylome and de-etiolation in plants.
